John McCain appears to be getting a considerable bounce from his victory in Florida, and the subsequent withdrawal of Rudy Giuliani, according to this poll conducted Jan. 28-30. McCain leads Mitt Romney 37 percent to 22 percent with Mike Huckabee at 17 percent. The interviews on the last day of the survey after Giuliani exited the race showed a significant increase in support for McCain.

On the Democratic side, Barack Obama keeps closing in on Hillary Clinton, narrowing her lead to 4 points. Clinton has 43 percent to Obama’s 39 percent. Her lead over Obama is the narrowest since early January. John Edwards still had 8 percent in the poll, but the last night of interviewing did not produce any clear signal about which way his supporters might jump.

The margin of error is 3 percent.
